Goals of this project include developing and improving coastal-change assessments and supporting long-term planning and decision making to ensure sustainable coastal economies, infrastructure, and ecosystems. Research is part of the National Assessment of Coastal Change Hazards...
Research to identify areas that are most vulnerable to coastal change hazards including beach and dune erosion, long-term shoreline change, and sea-level rise.
U.S. Geological Survey (USGS) Science Summary—New digital map documents surficial-aquifer thickness in the Delmarva Peninsula, Maryland and Delaware: Helping to understand the role of groundwater in delivering nitrogen to Chesapeake Bay
Nitrate, the major source of nitrogen in streams of the Eastern Shore of Chesapeake Bay and the wider Delmarva Peninsula, is transported primarily in groundwater through the unconfined surficial aquifer. Understanding the subsurface processes that affect nitrate transport in this area has been hampered by a lack of regional information on the thickness of this aquifer.
More than 30 years of data are available for many of the sites in the ASWQMN, making this network critical for the monitoring and analysis of long-term trends in water quality in New Jersey.
Federally-listed as threatened since 1986, the Atlantic Coast Piping Plover (Charadrius melodus) population comprises fewer than 2,000 breeding pairs, according to the most recent census data. These breeding pairs are the target of the U.S. Fish and Wildlife Service’s (USFWS) species recovery plan.
Preventing flood hazards, such as the hurricane induced storm surge, from becoming human disasters requires an understanding of the relative risks floods pose to specific communities and knowledge of the processes by which flood waters rise, converge, and abate. Scientific information and the development of new tools helps communities recover and become more resilient in the future.
Ground shaking caused by the sudden release of accumulated strain by an abrupt shift of rock along a fracture in the Earth or by volcanic or magmatic activity, or other sudden stress changes in the Earth.
The USGS reports document New Jersey floods from 1896 to the present. Early spring and winter flooding in New Jersey tends to occur as a result of widespread, steady rain of moderate intensity that falls on frozen ground. Snow and ice melt may increase the chance of winter flooding. Summer flooding resulting from thunderstorms typically occurs in small streams and is of local extent. Late...
No attempt has ever been made to regionalize low-flow relationships of New Jersey streams. Except at the approximately 100 continuous record and 300 partial-record sites distributed around the state, low-flow frequencies, such as the 10 year 7-day low-flows, are relatively unknown in New Jersey. Therefore, regional low-flow relationships that would allow an accurate estimation of low-flow...
